Answer:
m(∠ADB) = 25 degrees
m(∠BDC) = 35 degrees
Step-by-step explanation:
Measure of angle ADC of the logo = 60°
Measure of angle ADB = x°
And measure of angle BDC = (x + 10)°
Since, angle ADC is a combination of two angles,
Therefore, measure of angle ADC = m(∠ADB) + m(∠CDB)
x° + (x + 10)° = 60°
2x + 10 = 60
2x = 50
x = 25
Measure of angle ADB = x = 25 degrees
Measure of angle BDC = (x + 10)°
= (25 + 10)°
= 35 degrees
